(Z)-1-(3-Mesityl-3-methyl-cyclo-but-yl)-2-(morpholin-4-yl)ethanone oxime.

ABSTRACT: In the title compound, C(20)H(30)N(2)O(2), the cyclo-butane ring is puckered, with a dihedral angle of 19.60 (13)° between the two planes. In the crystal, the mol-ecules are linked by inter-molecular O-H⋯N and weak C-H⋯O hydrogen bonds, as well as a C-H⋯π hydrogen-bonding association.
